The POWERTEC Dust Control Flex Cuff with Hose Clamps, 4-Inch, is designed to deliver a secure, airtight connection between dust collection fittings of similar size, eliminating the need for tape or permanent fasteners. Its firm yet flexible rubber construction allows it to bridge slight diameter differences in hoses or tubing, ensuring a tight fit. The pre-molded indents make it easy to install the steel hose clamps for a quick and reliable connection. This set includes one rubber cuff and two durable steel hose clamps.
This dust collection fitting is perfect for transitioning from a 3-inch ID opening to a 4-inch flexible hose or standard 4-inch ID hose. The tapered port on one side fits into most 3-inch dust collection hoses, optimizing air velocity near your machine for improved dust collection. Crafted from premium ABS plastic, this fitting resists rust, corrosion, and stands up to the pressure of hose clamps and the abrasiveness of woodworking dust. The 4-inch nominal end measures 3-15/16 inches outer diameter and 3-45/56 inches inner diameter, while the 3-inch nominal end measures 2-63/64 inches outer diameter and 2-23/32 inches inner diameter.
POWERTEC is a leading manufacturer of high quality wood work accessories, sanding discs and an assortment of OEM replacement parts. We are committed to exceeding expectations, while bringing the latest innovations, technology, and product development to the industry.

Worked perfectly for my WeCreat Vista 10 exhaust hose. I previously purchased a dryer window vent kit that I used for my Glowforge Aura which has a much larger hose. The opening of the window vent was much too large for the hose of my Vista. This reducer helped tremendously !

Got a diesel heater with 3" output and balking at the price of 3" vent extensions? 4" is the universal cheap clothes dryer output and vent extensions of any length are available dirt cheap in that size. So what do you do. You get one of those guys for couple of bucks and free yourself to use that ubiquitous ducting.Sure, it would be nice if they used 4" off the hop, but when the design was stolen all those years ago, it must have used a 3" output, so the chinese clones use a 3" output today. This won't flow more air, nor will it restrict, but it will open up a myriad of cheaper options for routing heat. Does that job perfectly and I will get one for each heater.

Not all reducers are the correct size for true fit. This one is just abit smaller diameter. Perfect fit for aluminum and plastic hose. It took me lots of tries with other brands. This one was great.
